Abstract. A method of automated multi-program selective routing of digital signals in relation with their switching is proposed and analyzed. The structure of the signal is discrete periodic (packet). The situation of absence of a possibility of preliminary source synchronization is also considered. This is due to the need to use sources with arbitrary properties of the signal structure (frequency of packet movement, packet duration, consistency of the period of packet movement, etc.) and from different producers. Multi-user routing mode is also provided. Selective routing for subsequent transfer is provided after the selective synchronized switching of digital signals coming from a significant number of sources (1000 and more) is carried out.
